In case anyone is curious and doesn't know where to find the submissions for this year, here is the link:
The deadline was yesterday for submissions. It looks like 108 teams have submitted for the GIA this year (I think this is down from last year? archive.org showed at least 10 pages with 20 for filled pages and whatever would be left for the final page).
There appear to be a lot of interesting projects listed there.
Good luck to these teams and the 20 semi-finalists will be notified mid-April. Those semi-finalist teams are then invited to send representatives to the Washington, D.C. area for awards presentations, announcing of the winner and runners up, and other activities June 21 and 22.
Disclaimer: Yes, the team I coach is one of the submissions.
